QuestionAnswer
Too much volume in the vascular space Hypervolemia aka FVE aka Fluid Volume Excess;
Causes of FVE (Hypervolemia) CHF, Renal Failure, Alkaseltzer, Fleets enema, IVF w/Na, and Aldosterone
Alkaseltzer, Fleets ememas, and IVF w/Na have a lot of what? Na which in turn retains fluid in the vascular space
Where does aldosterone live? Adrenal glands
What is the normal action of aldosterone? When blood volume gets too low (vomiting, blood loss, etc.) aldosterone is kicked in which makes the body retain NA and H2O which increases blood volume
What are some dx with too much aldosterone? Cushings and hyperaldosterone (Combs)
What is a Dx with too little aldosterone? Addison's (add steroids)
Aldosterone = Na and H20
What do you get with too little aldosterone? Hypovolemia aka FVD aka Fluid Volume Deficit
What is ADH? Anti-Diuretic Hormone
What does ADH do to the body? Makes the body retain H20
What are 2 ADH problems? Too much and too little
Too much ADH causes what? Body retains H20 - creating FVE, SIADH can occur (too much H20), UO decreased and blood becomes dilute
What happens with too little ADH? Body loses H20 (diureses), creating FVD, DI can occur, UO increases and blood is concentrated
What is the #1 concern with FVD? Shock
Where does ADH live? Pituitary
What are key words to make you think potential ADH problems? Craniotomy, Head injury, Sinus surgery, Transphenoidal hypophysectomy (going through nose to take out pituitary)
What is another name for ADH? Vasopressin
What 2 drugs may be utilized as an ADH replacement in Diabetes Insipidus? Vasopressin and DDAVP (Desmopressin acetate)
If a ? is about UOP with a head injury - think what? ADH
Normal urine and blood do what? Mirror each other
ADH problems come secondary to what? Other major cause (they are sneaky)

Name some Diuretics? Loop (Bumex may be given when Lasix doesn't work), HCTZ and K-Sparing
With Diuretics, what do you want to watch carefully? Lab work, dehydration and electrolyte problems
What does bed rest induce? Diuresis (when you are supine, your kidneys perfuse more)
What are some interventions with FVE? Physical Assessment (think S/S) and Give IVF's slowly to elderly and very young
When a pt is on bedrest, what do you want to encourage? Fluids
What are some causes of Hypovolemia (FVD) Loss of fluids anywhere (not just blood), Thoracentesis, Paracentesis, Vomiting, Diarrhea, Hemorrhage, Third spacing (such as burns and ascites) and Dx with polyuria

Tx and Nursing Interventions for FVD? Mild deficit = push PO fluids. Severe Deficit = IV fluids
When vitals all go up = FVE
When vitals all go down, except HR increases = FVD
What is the first organ to die during shock? Kidneys
Isotonic = Goes into vascular spave and stays there!
Examples of Isotonic solutions: NS, LR, and D5W
Hypotonic = They go into hte vascular space, rehydrate, then move into the cell and the cell burns the remainder up in cellular metaboism. They do hydrate, but they won't drive your pressure up b/c they don't stay in the vascular space
Example of Hypertonic solutions: D10W, 3%NaCl, 5%NaCl, D5, LR, D5 1/2 NaCl, D5 NaCl, and TPN
Examples of Hypotonic Solutions: D2.5 W, 1/2 NaCl, 0.33% NaCl
Hypertonic Solutions = Pushing Pressure; Volume expander and solution that draws fluids into the vascular space

Always check what before and during IV Mg? Kidney function
Always put pt on what when receiving IV Ca++? Heart monitor b/c HR can drop and QRS can widen - a certain degree is appropriate - if too wide, give Epi & atropene, CPR and Code)
Hypo Mg and Hypo Ca++ will always be on what? Seizure precautions due to rigid and tight muscles
What do you do if your pt begins to c/o flushing and sweating when you start IV Mg? Assume the worst!
Your Na level in your body is totally dependent on what? How much H20 you have in your body
Hypernatremia = Dehydration (Too much Na; not enough H20)
Hyponatremia = Dilution (too much H20; not enough Na)
What are some causes of HyperNa? Hyperventilation (loss of H20 everytime you breathe), Heat stroke, DI
What are some causes of HypoNa? Vomiting, Sweating then drinking H20 (this only replaces the H20, not hte electrolytes), Psychogenic Polydypsia (loves to drink H20), D5W (sugar & H20), SIADH (too much H20 being retained)

What are the 2 major chemicals that must be remembered? Bicarb (base) and H, CO2 (acid)
What is the "lung chemical"? CO2 (acid)
What is the "Kidney chemical"? Bicarb and H (base and acid)
There is only one way to get rid of CO2 - what is it? Exhale
Bicarb, H+, and CO2 can either make you sick or compensate. It depends on what? On which IMBALANCE you have.
In Respiratory acidosis/alkalosis, which organs are sick? Lungs
During a chemical imbalance in the lungs - what organ compensates? The kidneys
What are the chemicals the kidneys use to compensate with? Bicarb and H+
In matebolic acidosis/alkalosis - which organs are sick? Kidneys
During a chemical imbalance with the kidneys - what organ compensates? Lungs
What is the only chemical the lungs have to compensate with? CO2 acid
Do the lungs compensate slowly or quickly? Quickly
Do the kidneys compensate slowly or quickly? Slowly (3 days - but efficient)
What is Normal pH? 7.35 - 7.45 (7.40)
In Metabolic Acidosis, what is sick, and what compensates? Kidneys are sick, lungs compensate
In Respiratory Acidosis, what is sick, and what compensates? Lungs are sick, Kidneys compensate
In Metabolic Acidosis What happens to the RR and why? RR increases to blow off CO2
In Resp Acidosis, what do the kidneys do to compensate? Retain/secrete Bicarb into the blood stream
In figuring out if something is Metabolic or Respiratory, what do you always need to remember? If all arrows are the same = M. If arrows are different = R. Look at pH level to determine if Acid or Alka
In Meta Alka, what is sick? Kidneys
In Resp Alka, what is sick? Lungs
In Resp Acid, what is the problem chemical? too much CO2 (acid) = RR too shallow or pt not breathing = kidneys will compensate
Increased CO2 = Decreased LOC and Decreased O2
What drug helps correct Acidosis? IV Bicarb
What's the first thing you think of with a restless pt? Early Hypoxia!!
Cyanosis + Bradycardia = Late Hypoxia!!
With a Hysterical pt, think? Resp Alkalosis (hypERventilation)
With Resp Alka, how do you treat? The kidneys will take 3 days to compensate, therefore have pt breathe into paperbag to force them to take back in CO2. Sedate pt if needed to slow down RR
If a pt is starving, what do you think? Meta Acidosis. The fat is being broken down, therefore producing keytones, and keytones are acid
When a pt is vomiting, what do you think? The body is losing acid, leaving the pt alkaline, therefore Meta Alkalosis
Pneumothorax = Resp Acid
Pneumonia = Resp Acid
Alka Seltzer / Antacids = Meta Alka
NG to suction = Meta Alka
Contusion to lung parenchyma = Resp Acid
Broken Ribs = Resp Acid
Pt getting lots of IVP Bicarb = Meta Alka
Acidosis = Hyperkalemia (acidosis makes K+ leak out of cell)
Alkalosis = Hypokalemia (alkalosis pushes K+ back into the cell)
Highest risk of death with a burn is with what population? Very old and young
Where so burns most occur? In the home
With a burn, why does plasma seep out into the tissue? Increased capillary permeability
When does the majority of plasma seepage occur with a burn? In the first 24H
Why does a pt's pulse increase with a burn? Anytime you're in a FVD, pulse increases to compensate
What does the UO decrease with a burn pt? Kidneys are either trying to hold on or they aren't being perfused
What is epi secreted in a burn pt? Makes the ot vasoconstrict, shunts blood to vital organs
Why are ADH and aldosterone secreted with a burn pt? to retain Na+ and H20 with aldosterone and retain H20 with ADH = therefore the pt's blood volume will go up
What is the most common airway injury with a burn pt? Carbon Monoxide poisoning
Tell about CO binding with burn pt's Normally O2 should bing w/hemoglobin. CO can run much faster then O2...therefore, it gets to the hemoglobin 1st & binds
Can CO levels be determined with a pulse Ox (pulse sat)? NO, the pulse ox just shows how much hemoglobin is bound - but bound to what we don't know
What determines how much CO is bound in a burn pt? Carboxyhemoglobin; blood test to determine carbon monoxide poisoning
If pt is hypoxic, what is the Tx? 100% O2 (the ONLY time a pt is allowed 100% levels)
Why should you always determine where a burn occured? If open space, <chance of CO poisoning. If closed place, >chance of CO poisoning
When you see a pt with burns to the neck / face / chest you had better think of what? Airway! May need to intubate then trach
A pt is burned over 40% of their body. How is that figure determined? Rule of nines
Rule of nines: Head = 9
Rule of nines: Each arm = 9
Rule of nines: Each leg = 18
Rule of nines: Anterior trunk = 18
Rule of nines: Posterior trunk = 18
Rule of nines: Genitalia = 1
One of the most important aspects of burn mgmt is what? Fluid Replacement
Why is albumin given after a major burn? Albumin holds onto fluid in the vascular space
What effect does albumin have on the kidneys w/ a burn pt? It increases kidney perfusion
What effect does albumin have on BP w/ a burn pt? Increases BP
What effect does albumin have on Cardiac Output w/ a burn pt? Increases CO
When giving a burn pt albumin, why do you really have to watch the heart? When you give albumin, the vascular volume will increase, therefore increasing the workload of the heart. The heart could be stressed, causing FVE
If FVE happens with a burn pt, what happens to the cardiac output? It decreases. You will hear wet, crackle sounds
On any pt who is receiving fluids rapidly, what must be monitored so overload does not occur? CVP (Cardia Vascular Pressure)
Why is it important to know what time the pt's burn occured? Fluid therapy (for the 1st 24H) is based on the time the injury occured, not when Tx was started
If a burn pt's CVP increases suddenly during IV fluids, what do you watch for? R sided Heart failure
What is the Parkland Formula for Burn Pt's? Calculate what is needed for the first 24H and give 1/2 of it during the first 8H, 1/4 of the total volume the 2nd 8H, then the remaining 1/4 the 3rd 8H
To calculate fluid replacement for burn pt's (Parkland Formula) what do you need to know? The pt's weight in kg and TBSA (total body surrface area)
If a burn pt is restless, what 3 things could it mean and which is PRIORITY? Fluid replacement is inadequate, pain or hypoxia. Hypoxia is priority
Always check what to determine if a burn pt's fluid volume is adequate? UO
A pt was given only 5mg of Morphine when the order was for a max of 10mg. Why did the nurse do this? The pt's RR is shallow; give the least amt first; use judgement
Why are IV pain meds preferred over IM with burns? They act faster. No muscle with good perfusion for IM
Why is a burn pt given a tetanus toxoid + the immune globulin? For antibodies
Explain the Tetanus Toxoid shot with burn pt's? Active immunity; takes 2-4 weeks to get the AB's
Explain the Immune Globulin with burn pt's? Passive immunity; think immediate protection
Does more death's occur with upper or lower body burns? Upper; b/c of airway
A pt has a circumferential burn on their arm. What does this mean and what should you be checking? a burn all the way around the arm and cuts off circulation. Check skin color, skin temp, capillary refill, and pulse
If a pt's vascular checks in his burned arm (circumferential) are bad, the Dr may do what procedure to relieve pressure? Escharotomy or Faciotomy
A pt was wrapped in a blanket to stop the burning process. Since the flames were gone does that mean the burning process had stopped? No (apply cool H20 also)
What purpose does blankets on a burn pt do? Stops the flames, holds in body heat and keeps out germs
Can ice be put on burns? NO, ice will cause vasoconstriction therefore cutting off circulation
Why is it important to take off jewerly on a burn pt? Swelling
What things do you look for to determine if any airway injury has occured w/ a burn pt? Soot on face, dark sputum, synged facial/nasal hair
Is a foley inserted with burn pt's Yes and measured hourly. Brown/red UO is normal after a major burn, but still worry
Is it possible that when you insert a foley on a burn pt that no urine will return? Yes due to kidneys attempting to conserve the fluid or not perfusing properly
What drugs might be ordered for a burn pt to help kidneys perfuse? Lasix, Butnex, Dobuatonine, Dopamine
Why will a burn pt start to diurese after 48H? Because the fluid is going back into the vascular space. Now worry about FVE. UO should increase during this time
K+ always like to live where? Inside the cell
Pot is IN, Na+ is OUT Pot is IN, Na is OUT
With a burn, what happens to the cells? Rupture
What happens to serum K+ levels during a burn? It increases. The K+ seeps out of the cell and into the vascular space
Watch K+ levels to go which way with burn pt's? HypERK+
Why is Mylanta, Protonix, Pepcid, and Reglan ordered for burn pt's? Curling or stress ulcers
Name 4 Antacids: Aluminum hydroxide, Amphogel, magnesium hydorxide and Milk of Magnesia
Name 3 H2 Antagonist: Zantac, Pepcid and Axid
Name 2 PPI's: Protonix and Nexium
Why would a Dr want a burn pt to be NPO and have an NGT hooked to suction? Paralytic Ilius
If a burn pt doesn't have bowel sounds, what will happen to the addominal girth? It will increase
Will a burn pt need more or less calories than before the burn? More calories
If a burn pt has an NG tube, when will it be removed? When bowel sounds are present
When you start GI feedings with a pt, what could you measure to ensure that the supplement was moving through the GI tract OK? Check residual. If too much residual present, pt can vomit and could aspirate
What must you always do when checking residual with a GI tube? Put the residual back in pt

What is also used to debride eschar from burn pt's? Hydortherapy
What must be done before ANY debridement is done with burn pt's? Give pain meds and allow them to kick in
What are the 4 Common Drugs used with burns? Silvadine, Sulfamylon, Silver-nitrate and Betadine
Describe the drug Silvadene: For burns, soothing, spply directly, if rubs off apply more, can lower the WBC, can cause rash
Describe the drug Sulfamylon: For burns, can cause acid-base problems, stings, if it rubs off apply more (check allergy to sulfa????)
Describe the drug Silver-Nitrate: For burns, keep these dressings wet, can cause electrolyte problems
Describe the drug Betadine: For burns, stings, stains, allergines, can cause acid-base problems
What should the 4 common Burn drugs be alternated? The bacteria will build a resistance
Why will broad spectrum antibiotics be avoided with burn pt's until the wound cultures have returned? To prevent super-infections
If grafting is done on a burn pt, a pressure dressing will be applied is surgery. At what point will the wound be left open to air? When the bleeding has stopped
If a skin graft with a burn pt becomes blue or cool, what does this mean? Poor circulation - CALL DR!
Sometime with a burn pt, the Dr will order for you to roll sterile Q-tips over the graft with steady, gentle pressure from the center of the graft to the outer edges. Why? So new skin will adhere

If you get an artery question... Figure out what that artery feeds - that will be the answer
Seek out depressed pt's... Get out from the nurses station
When dealing with suicide pt's, be very .... Direct such as "Are you thinking of killing yourself"?
When using retraints, always use as... The last resort and always check 1) Hydration, 2) Nutrition, and 3) Elimination
When a pt needs to exercise anger out... Pick the answer that exerts the most energy without harm to pt or others (punching bag)
When a pt is having a hallinication... Get them out of the hallway and back into reality
When putting pt's in room assignments... Like illnesses can be placed together - EXCEPT HIV
Plan to protect your pt, even when you are not there... Always plan that the next nurse is not very bright
On giving report, plan that the next nurse is not very bright... Give the most life threatening info first
When a pt is given normal S/S in an NCLEX question... Red flag
Never decrease CO in pregnant women... Fetus will not get blood

What are the S/S of Addison's? Anorexia/N, Decreased bowel sounds, GI upset, Hypoglycemia, Dark palms, Vitiligo (white patchy areas on skin)
When you hear Addison's Dx, what hormone should you think of? Aldosterone = Normally Aldosterone makes us retain Na+ and H2O and lose K+, this is NOT happening, it is opposite
What is the Tx for Addison's? Prevent shock! Losing Na+ and H2O, pt's BP will be going down due to FVD
It a pt soes not have enoung Aldosterone (Addison's Dx), what drug will be given? Florinef

What is hte RULE with weight and meds? Keep pt's weight within +- 2lbs of their norm
Addison's Crisis = Severe HypoTSN and Vascular Collapse
Why must Steroids be tapered off? When giving synethic steroids, your Adrenal Cortex stops making them, if stop abruptly, you will have NONE
Are steroid doses always chaning? Yes
Cushings Syndrome = Too MANY steroids (opposite of Addisons) : Exogenous administration such as someone taking steroids for something
Cushings Dx = Too many steroids (opposite of Addisons) : Endogenous (inside body such as bilateral adrenal hyperplasia, etc...
S/S of too many Glucocorticoids (Cushings) Growth arrest, Thin extremities/skin, Increased risk for infection, Hyperglycemia, Psychosis to depression
S/S of too many Sex Hormones (Cushings) Central obesity, buffalo hump, heavy trunk, oily skin.acne, women w/male traits, Poor sex drive

Anytime steroids are messed up = pt can not handle stress
Steroids decrease what? Ca++ by making you excrete it through GI tract
What may be he first sign of Type 1 Diabetes? DKA
What is hte patho pf DKA? Since there is no insulin, hte glucose just builds up in the vascular space (blood)...the cells are starving so they break down protein/fat for energy...when you break down fat you get keytone acids...now pt is in Metabolic Acidosis
Hyperglycemia = 3P's
What are the 3P's with Hyperglycemia? Polyuria, Polydypsia and Polyphagia
What is the Somogyi Phenomenon? Type 1 pt has normal and increased BS at bedtime, then BS drops in early am (~2-3am). Pt's body attempts to compensate by producing hormones to increase BS resulting in HYPERGLYCEMIA
What is the Tx for Somogyi Phenomenon? Increase bedtime snack and decrease intermediate acting insulin (NPH, Lente)
What is the Dawn Phenomenon? Resulting from a decrease in the tissue sensitivity to insulin that occurs between 5-8am (prebreakfast hyperglycemia) caused by a release of nocturnal growth hormones
What is the Tx for Dawm Phenomenon? Give intermediate-acting insulin (NPH, Lente) at 10pm
Polyuria --> Oliguria --> Anuria
Polyuria --> Shock

Why are diabetics prone to CAD? Sugar deposits destroys vessels just like fat
Why should diabetics be on a high fiber diet? It keeps the BS steady (may have to decrease insulin). High fiber slows down glucose absorption in the intestines, therefore eliminating the sharp rise/fall of the BS
What should the diabetic do pre-exercise to prevent hypoglycemia? Eat a low carb snack
A diabetic should exercise at what BS point? the highest
The diabetic should exercise at regular times, why? you can train the BS
**How do you give mixed insulins????? Air in cloudy, air in clear, draw up clear, draw up cloudy
What insulin is clear? Regular
What insulin is cloudy? NPH
What is the only type of insulin that can be given IV? Regular
What is the Hemoglobin A1C test? Blood test: gives an average of what the BS has been over the past 3 months
Diabetics should eat when? When insulin is at it's peak: "Peak" = think Hypoglycemia
What happens to BS when you are stressed /sick? It goes up; probably will need to increase dose
Should you aspirate insulin? No, too much tissue trauma
What are the S/S of Hypoglycemia? Cold, clammy, weakness, nervous, increased pulse, nausea, confusion, headache
What should the pt with hypoglycemia do? Eat a simple sugar fast
You enter a pt's room and they are unconscious...do you treat as Hyper or Hypoglycemia????? Hypo; that is the worst, brain damage. Give D50W, injectable glucogon when no IV site accessed
Diabetes + illness = DKA
With every drop in BS, pt loses what? Few brain cells
What are the IVFs with a pt in DKA? Start w/NS, then when BS gets down to about 300 switch to D5W to prevent throwing the pt into Hypoglycemia (anticipate the Dr will order Ka+ to the IV solution at some point)
What is HHNK? Looks just like DKA, but no keytones (acidosis)
DKA = Type 1
HHNK = Type 2
Diabetics will have what other problems related to Dx? 1) Vascular problems (poor circulation, diabetic retinopathy, nephropathy), 2) Neuropathy (sex problems, foot/leg problems, neurogenic bladder, gastroparesis), 3) Increased risk for infection (full of sugar)
